I don't see any scenario under which a Black man,regardless of any degree of Italian lineage would ever be made.
The Mob is not about "political correctness" or Equal Opportunity.
There is one reason that a Black man could not be made.and it's very simple - he"s Black. Fair or not,like it or don't,that's the deal.
To Italian gangsters, making a "mulinyan" (their word,not mine) would be worse than making a woman.
No respect from other made guys in the same family, and certainly not from any other Family.
